just kind of a curiouse question. are there any games or applications that only work with older versions of dos? i ask because i've read a few sources that reccommend useing dos 5 over 6.22 but is this purely just for the sake of doing something diffrent or do some games acually run better in dos 5? is dos 6.22 much more taxing on say, a 386 pc then if you installed 5?
